Embedded loop delay compensation circuit for multi-channel transceiver

摘要

A circuit for measuring and compensating for propagation delays in a communication system is described. In communication systems such as wireless networks a number of base stations operate within cells to provide wide area coverage. In such systems a base station controller will communicate with each base station to provide certain information including a synchronizing time stamp. When the distance between the base station controller and each of the individual base stations is not a constant a propagation delay introduced by this distance differential will mean that the time stamp transmitted from the base station controller will not reach all the base stations at the same time. This invention relates to a system and method of measuring respective propagation delays and for introducing a compensating value.
